Lovely company to deal with … took the trouble to include a personal note and a smiley face, which is always a good sign of exemplary Customer Service! More importantly, they are Trusted Partners for this Knock Aergrind, which is only available in small numbers. They had it in stock … postage included … and even included a bag of their Colombian beans (a tenners worth). So what’s not to like!


Excellent grinder.Exceptional quality with great results.

Happy customer.

I'm so glad to have this grinder as part of my daily coffee routine! It's a great build quality and grinds so swiftly. A huge upgrade from my last hand grinder which was like a morning workout!! The stepped adjustments for grind size are easy to navigate too, allowing me to dial in different beans from my monthly subscription with ease. Thanks Dear Green! You've nailed it again!

Great feedback on one of our favourite products! Thanks so much Theo!
